5 equipments really function well and guarantee
the users’ safety? This is a question that always concerns the users and others that need further investigation. It is very dangerous
if the safety does not enhance strictly and ergonomically. The accidents or injuries can not be expected but safety can be learned to avoid it. The ergonomics work improvement
in the welding shop should be proposal and implement efficiency, so that the risk of accidents or injuries can be reduced and provides a healthy welding working
environment to the users.
The project is carried out by using the postural analysis tools in observation method to access working posture of the users. The data checklist shows the problems
confronted in welding workshop and gives the ideas for making improvement more easily since the problems exists is verified. In the other hands, the analysis of the
working posture users is done by photo capture and orientations of body posture of the images of working postures that have been captured is measured by using the protractor.
Data requirements is key in to the Ergoweb software to determine safe or unsafe postural of users. The data is then revised few times to provide the correct posture suggestion for
user. Proper ergonomics solutions are found to solve the problems confronted so that the users can avoid themselves from injuries and accidents and work under comfort working
environment. Welding users need good eyesight, hand-eye coordination, and manual dexterity. They should be able to concentrate on detailed work for long periods and be
able to bend, stoop, and work in awkward positions safely.
1.2 Problem Statement
Commonly the users or welder that operate with the welding machine or working under welding heat stress in the workshop will confronted or experienced with various
types of diseases or injuries which can be classified as physiologically and psychologically injuries. They will more experienced in musculoskeletal Disorder,
Repetitive Strain Injuries, low back pain, Cumulative Trauma Disorder, eye pain, skin in
6 burns from hot metal, spattering slag and from handling hot tools or electrodes or even
from ultra light. These indirectly influences daily life such can not concentrate well in their works because of the injuries suffer. It should be thinking deeply about these
questions such have the safety rule obey by user or enhance strictly by superiors to protect users from injuries? Why most of the users still feel discomfort after welding
activities? Why still many users are infected with diseases such as red eye discomfort, wrist and shoulder pain under static posture for long period and others diseases although
they have obeyed to the safety rules? Are the problems exist cause of the poor design of the personal protective equipments in the workshop? All of these questions need to
investigate seriously to improve human safety in workshop in order to reduce the risks of injuries. Workbench design and use of positioning aids to accommodate work posture
in the welding workshop are not efficiency. There are just has standing workbench design in the workshop and really a burden to the users to work in long term duration.
The poor ventilation system in the workshop brings the effect to the respiratory human and the poor designed canopy hook makes contaminant can’t removes away from the
breathing zone of the operator easily. Although most of the safety devices have been provided in the workshop but the concept about ergonomic safety do not enhance well
and hence affect performance of the welders in their work. The ergonomics concept should be introduced so that users can practice healthier life and avoid from injuries
when conduct their works in welding workshop.
